45_09/2006Cover Picture: Asymmetric Intramolecular Crossed-Benzoin Reactions by N-Heterocyclic Carbene Catalysis (Angew. Chem. Int. Ed. 9/2006)

Enantioselective intramolecular crossed-benzoin reactions can be effected by using chiral N-heterocyclic carbene catalysts. The tetracyclic chiral carbene catalyst shown in the cover picture enables the reaction to proceed with formation of only one enantiomer of the α-hydroxy-substituted tetralones. D. Enders and co-workers disclose the development of the quaternary stereocenters in the organocatalytic reaction in their Communication on page 1463 ff.
